Abstract:
The present invention provides a device and method for electromagnetic induction heating-assisted laser additive manufacturing of a titanium matrix composite and belongs to the technical field of laser additive manufacturing. The device includes a coaxial-powder feeding laser deposition system and an electromagnetic induction heating synchronous auxiliary system. The coaxial-powder feeding laser deposition system includes a substrate, a deposition sample, a laser head and an infrared thermometer. The electromagnetic induction heating synchronous auxiliary system includes an electromagnetic induction power supply auxiliary unit, a coil, a steering heightening mechanism, a driven shaft and a transverse sliding groove. The coil is connected to an output end of the electromagnetic induction power supply auxiliary unit. The coil and the laser head do synchronous movement to implement small-area real-time preheating and slow cooling on the deposition sample.
